HE APOLLO is an indirect lighting unit with luminous 

bowl. About 17.5 of the light is transmitted downward 

through the bowl and 82.5 upward, softly and uniformly 
illuminating the ceiling. 


Heretofore, indirect lighting units have thrown a bright, well- . 
defined spot of light above them. The APOLLO is so designed 
that the uncontrolled light from the inner bowl is bent upward 
by the outer bowl and dissolves the edge of the spot made by 
the inner reflector. The result is a lighted area that softly 
fades until the walls are reached. 


In the past, lighting units of the luminous-bowl indirect type 
have employed dense absorbing mediums to keep the brightness 
of the bowl below permissible values. The combined action of 
the reflecting and refracting prismatic construction of the 
APOLLO Unit is to lower the brightness of the bowl to 2.6 
candles per square inch without excessive absorption. The light 
which would ordinarily produce excessive brightness of the bowl 
is refracted to the ceiling. 


There is neither direct nor reflected glare from the unit due to 
its low intrinsic brilliancy. Its average brightness is similar to 
the ceiling so that there is no objectionable contrast but instead 
the unit blends with the surroundings. 


The APOLLO can be accommodated to varying sized rooms and 
different ceiling heights. For low ceilings and small rooms the 
ceiling unit should be used. For high ceilings and large rooms 
the canopy and holder can be separated, and a chain, cord or 
rod support of the proper length inserted. 


All glass surfaces exposed to the air are smooth. The space 
between the two bowls, shown in Fig. |, page 7 is sealed at the 
top with the white enameled diaphragm and at the bottom with 
the finial. The unit is thus, for all practical purposes, dustproof. 


The dust that may collect in the small cup formed by the inner 
bowl can be easily removed by first releasing a hook catch and 
then wiping the inner bowl with a damp cloth. 


Git APOLLO -s) 





The materials used in the manufacture of the APOLLO are 
permanent in their nature. There is nothing to deteriorate, 
nothing to rust, nothing to decay. A decade from now the 


APOLLO will be as efficient, and as good as when first installed. 


The advent of the APOLLO brings within reach of everyone 
the limitless possibilities of TINTED LIGHTING. By placing 
a color filter of sheer silk or some similar translucent material 
around the inner bowl the outer bowl can be beautifully and 
delicately tinted. Thus the soothing atmosphere of the rest- 
room and the hotel bedroom, the chic feeling of the dressmaker’s 
salon, the gay air of the cabaret, and the reverent dignity of the 
church can all be expressed more definitely by the use of the 
appropriate color filter in the APOLLO. 


To recapitulate, the APOLLO: 


1. Lights the ceiling without objectionable spot or shadow 
effects, softly and comfortably. 


2. Has the ideal distribution for indirect lighting, putting 
the light where it is wanted. 


3. Is glareless. 


4. Can be accommodated easily to varying sized rooms and 
different heights of ceiling. 


5. All prismatic surfaces are sealed from contact with 
the air. All outside surfaces are smooth and easily 
cleaned. 


6. Is made to stand up and give full performance 
continually. Is durable and permanent. 


7. Is highly efficient—approximately 85%. 


8. By the use of color filters and silk or parchment shades 
it permits expression of individuality.

HOW TO MAKE ADJUSTMENTS 


ON CEILING UNIT: 


For different sizes of bays: The 12-inch APOLLO, assembled as shipped, 
will properly light bays of ten feet diameter. The 16-inch APOLLO, 
assembled as shipped will properly light bays of sixteen feet diameter. 
For larger ceiling areas the suspension type unit should be used. 


ON SUSPENSION UNIT: 


For different sizes of bays: Raise or lower the unit by reducing or increas- 
ing the length of the supporting chain, cord or rod. 


FOR DIFFEREN BesiZessOr EAMES: 


The 12-inch APOLLO is shipped set for 100-150 watt, ““C” lamps. 
The 16-inch APOLLO is shipped set for 200 or 300 watt “‘C’”’ lamps, accord- 
ing to the order. 


FOR CHANGE FROM CEILING UNIT TO SUSPENSION UNIT: 


Remove lock nut which clamps canopy to holder and attach loops and 
chain supplied with suspension type APOLLO units.

GOUOR RIN SELGE TING 


AINTING with light” is a phrase that has recently 
achieved popularity in the lighting field. It has made 
articulate a feeling, a desire for the beautiful in lighting 
that has steadily grown for years. Until the advent of the 
APOLLO that desire could only be met in unsatisfactory ways. 


Today the APOLLO brings all the wealth of infinite atmospheres 
that the world of color puts at one’s command, into the every- 
day shop, the office and the home. 


The mistress of the house can exactly match her lighting furnt- 
ture with her household furniture. Whatever the color of her 
draperies, table covers, cushions or upholstery, that hue can be 
given to the APOLLO, and by the mistress herself. Should she 
decide to change the decorations of her home, to bring the 
APOLLO into harmony with her new color scheme all she has 
to do is to replace the old color filter with the proper new one. 


The lawyer, the physician, the architect and others whose 
offices have distinctive, individual appearances can all add 
greatly to the special purpose and appeal of their surroundings 
by the use of appropriately tinted APOLLOS. 


The milliner’s, the modiste’s; the candy-shop and the tea-room; 
the florist’s and the haberdasher all have a definite individual 
“air’’ to which the APOLLO can be exactly adapted so that one 
might say “it is born to its surroundings.” 


An additional, welcome refinement can be had in the use of silk 
or parchment shades, silk or metal fringes, metal or glass beads, 
or crystal ornaments suspended from the lip of the APOLLO in 
a way to exactly catch the spirit of the interior.

APOLLO ACCESSORIES 
HE APOLLO lends itself to “decorative treatments.” The lip of the 


outer bowl forms a support upon which any ornamental embellishment 
on a wire frame can be hung. Thus, by dressing the unit with a silk or 
parchment shade, or silk tassels or fringes, or beaded loops, the little 
extra touch can be added to harmonize the unit with any interior.
